Improving BDS-2/3 satellite clock bias prediction using a TCN-Transformer framework with cross-attention mechanism

Satellite clock bias (SCB) prediction is essential for enhancing the accuracy and reliability of real-time precise point positioning (RT-PPP) in Global Navigation Satellite Systems (GNSS). To address the nonlinearity, non-stationarity, and short-term interruptions of SCB data under complex environme...
